Abstract: According to the energy waste, bigger burden and the different requirements of different injection pressure in the process of injecting pressure, this paper has conducted an in-depth study and put forward a series of new and improved technologies based on the original technologies, and the new techniques are validated, using modelling and simulation, and ultimately a set of hydraulic and automatic pressure regulating energy-saving water injection technologies for ground water injection are formatted, which can transfer a low-pressure well's surplus energy to high-pressure well without adding new equipment's energy consumption, complete the redistribution of the water injection pressure between high- and low-pressure wells, and realise the reasonable energy conversion between wells. All in all, it is of great significance to further improve the qualified rate of interval, saving energy, and reducing consumption of water resources.

Keywords: water injection well; pressurised water injection; double action; stable pressure; early warning.
